I UBRIGATOR.

means of which the quantity of oil or lubrir cant permitted to pass at any one time from the storage-reservoir to the oil-cups of themachinery may be accurately gaged or regulated, thereby insuring the supply of the necessary quantity of oil required at any one oiling and at the same time avoiding the wasteful use of the lubricant.

' The object of my invention is to construct a lubricator of this class which shall possess superior advantages in point of simplicity,

durability, ease and certainty of operation, and general efficiency, in which, moreover, the working parts of the device, as well as the lubricant, shall be protected from the weather, thus avoiding the 'annoyances oftentimes caused by dust, rust, and the like.

With these and other ends in view my invention consists in the improved construetion, arrangement, and combination of parts, which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical sectional view of a lubricator constructed in accordance with the principles of my invention. Fig. 2 isa sectional view taken on the line 2 2 in Fig. l. Fig. 3 is a sectional view taken on the line 3 3 in Fig. 1.

Fig.' 4 is a perspective view showing the valve l detached.

l designates a storage tank or reservoir which is provided with a horizontal partition 2, whereby it is separated from the measur- 5o ing-chamber 3, the bottom of which, is preferably funnel-shaped, as shown. The tank l, which is preferablycylindrical in shape,is provided with a cover 4, tightly iitting, so as to eX- clude foreign matter. The partition 2, which constitutes the bottom of the tank, is provided 5 5 with a central screwthreaded opening 5, which may be surrounded by a strengthen ing-flange 6A and which receives the valvecasing 7. The latter is provided with a bore S, the lower end of which is enlarged to form 6o a chamber 9, which is connected with the eX- terior of the valve-casing by inclined perforations 10. The valve ll,which is mounted in the casing, is provided with an upwardlyex` tending stem 12, upon which is coiled a spring 6 5 13, capable of being compressed by means of a nut let and washer 15 against the upper side of the valve-casing, so as to force the valve in an upward direction against the seat 16 at the lower edge of the casing, a washer 17 be- 7o ing placed on the valve to form a tight joint with the seat. The walls of the valve-body are provided with vertical grooves or oil-duets 18. lThe lower edge of the valve has an annular groove 19, in which is seated ra. washer 20. A recess 21, extending from thebottonr upwardly into the valve, terminates in a reduced screw-threaded portion22, engaged by the threaded end of the operating-rod 23, which extends downwardly through a stand- 8o pipe 24, rising from the feed-head 25 and extending into the lower end of the recess 21 in the valve. This stand-pipe serves to prevent overflow and waste of oil adjacent to the operating-rod, and it also serves to guide the 8 5 valve, as will be presently more fully described. The bottom 3IL of the measuring chamber has a screw-threaded flanged opening 26 to receive. the casing 2,7, which constitutes the lower valve-seat and which is 9o connected by a pipe 2S with the feed-head 25, from which the aforementioned stand-pipe 23 extends through said pipe 28 upwardly into the recess 2l of the valve. Y It will be seen that by exerting downward pressure upon the operating -rod 23 the valve will be. pulled downwardly and will be guided by the standpipe 23, engaging the recess 21, to a seat 29 at the upper edge of the casing 27. A washer 30 is interposed to make a tight joint between roo the latter and the iange 31, surrounding the threaded opening 26 in the bottom of the measuring-chamber.

The feed-head 25 is simply a chambercd easing forming an enlargement at the lower end of the pipe 2S and provided with a plurality of screw-threaded openings 31 of varying diameters, in which are iitted the upper ends of feed-pipes 32, likewise of varying diameters and through which the oil is conducted to the oil-ducts. Thus a large conducting-pipe 32 may be connected with a group of small oil-cups, while a large oil-cup may be fed by an individual pipe. In this manner the quantity of oil fed to the different oil-cups may be regulated, as will be readily understood.

The operation and advantages of this invention will be readily understood from the foregoing description, taken in connection with the drawings hereto annexed. It is obvious, in the first place, that the measuringchamber may be made of any desired size to hold the exact quantity of oil required to be conveyed at one time to the oil-cups of the machinery in connection with which my improved lubricator is used. To operate the device, the operating-rod 2S is pulled downwardly against the tension of the spring 13 until the valve 11 engages the seat 29. Vhile the Valve is held in this position the contents of the tank or reservoir will pass through the openings 10 of the upper valve-casing and through the `grooves 18 of the valve into the mixing-chamber. lVhile the valve is held in this position it is obvious that no oil will be permitted toescape thro ugh thepipe 23 to the feedhead, thev upper end of said pipe being closed by the valve engaging the seat 29 of the lower valve-casing. B y making the openings 10 and ducts or grooves 1l of the proper size only a few moments will be occupied in the filling of the measuring-chamber, after which the operating-rod is released. The tension of the spring 13 will restore the valve to its normal position, as illustrated in Fig. 1 of the drawings, when the communication between the reservoir and the measuring-chamber will be cut olf by the engagement of the valve with the seat 16 ofthe upper valve-casing. Vhen the valve occupies this position, the contents of the measuring-chamber will pass through the pipe 2S to the feed-head, whence it is distributed through the pipes 32 to the oil-cups of the machine. rIhe stand-pipe 24, as hereinbefore stated, serves as a guide to the valve and also to prevent overflow adjacent to the operating-rod of the device.

It will be seen that in this improved lubrica-tor none of the working parts are exposed, the valve, as well as all of the working parts, being inclosed within the outer casing of the device. My improved lubricator may therefore be used in the most exposed positions without the least danger of getting out of order or of any of its parts being injuriously affected by the weather.

The device is exceedingly simple in con- I have in the foregoing described the pre-l ferred form of my invention; but I desire it to be understood that I do not limit myself with regard to the exact mode of construction herein shown and described, but reserve the right to any structural changes and modifications that come within the spirit and scope of my invention and which may be resorted to without sacrificing the utility of the same.
